Two Cases of Medial Displacement of the Superior Cornu of the Thyroid Cartilage without Laryngeal Injury Resulting in Foreign Body Sense in Pharynx and Larynx / 대한이비인후과학회지

ABSTRACT

Foreign body sensation is a nonspecific symptom of aerodigestrive tract diseases. Symptoms may be the result of gastroesophageal reflux, esophageal motility disorder, psychological factor and malignant lesion. Rarely, a unilateral bulging of the hypopharynx as a result of medial displaced superior cornu of the thyroid cartilage can be a reason. The appropriate diagnosis is made by fiberoptic laryngoscopy and CT scanning. Surgical removal of the portion of the superior cornu bulging toward the hypopharynx improves the foreign body sensation. We experienced two cases of medially displaced superior cornu of the thyroid cartilage without laryngeal injury. This unusual presentation is discussed with a review of the literature.
